Analysis and Synthesis of MOS Translinear Circuits

The translinear (TL) circuit principle was first formulated as a practical means of implementing nonlinear signal processing functions by bipolar analog electronic circuits. In Analysis and Synthesis of MOS Translinear Circuits it is shown that a generalized interpretation of the TL principle leads quite naturally to an extension to MOS circuits. The square-law characteristic of MOS transistors operated in the saturated region is exploited. This results in nonlinear signal processing functions different from those provided by bipolar translinear circuits which are based on the exponential current--voltage characteristic. Analysis and Synthesis of MOS Translinear Circuits starts by deriving the MOS Translinear principle and investigating the effects of transistor nonidealities. A systematic approach to analysis is developed based on a graphical method which is easy to visualize. The graphical method is implemented in a computer-aided analysis program. The most important part of the book concerns circuit synthesis. Design strategies are presented, which are illustrated by the design of various useful circuits: an output stage for CMOS opamps, a four-quadrant multiplier and a variable-gamma circuit for color television. A number of new nonlinear building blocks are also present. Analysis and Synthesis of MOS Translinear Circuits is a valuable reference resource for designers of analog electronic circuits and researchers in analog electronics. It is also suitable for use as a text in advanced courses on the subject.
